Welcome to AOP 2019

The world of Optics and Photonics meet in Lisbon, Portugal, from the 31th May to the 4th of June 2019, at the IV International Conference on Applications in Optics and Photonics, AOP 2019!

The present scientific activity is the 4th edition of successful meetings, which started upon the extraordinary success of the first International Conference on Applications in Optics and Photonics, AOP2011, organized by the Portuguese Society for Optics and Photonics, SPOF, at the University of Minho
(www.optica.pt/aop2011), followed by a second edition in Aveiro (www.aop2014.org)and a third in Faro (www.aop2017.org).It will be the major optics conference in Portugal next year and one of the most important at world level, aiming at discuss the recent progress and to establish a view on the future of all fields of optics and photonics.

Lisbon is the capital and the largest city of Portugal. Boasting over 20 centuries of history, its traditional neighbourhoods with steep, narrow streets, with their characteristic cobblestone pavements, unique in Europe, and the tile panels on buildings, are all part of Lisbon’s incredibly acquired heritage over time. In the historical centre of the city you can still enjoy the richness of the music declared intangible cultural heritage of humanity by UNESCO, the “fado”.

Surrounded by the Tagus River, the riverside area features large gardens and imposing monuments, such as the Jerónimos Monastery, the Monument to the Discoveries or the Belém Tower. The main factory of the traditional and delicious “pastel de Belém” is located in this neighbourhood.

In the most contemporary part of the city there is Parque das Nações, a lively, dynamic and multifunctional area, characterised by the modern architecture of the buildings and by the diverse infrastructures and green spaces for leisure and recreation.

Further afield in the suburbs, you can enjoy the long sandy shores, either to relax or practice sports, as well as the stunning protected landscapes or the picturesque rural landscapes. There are also to discover various monuments classified as world heritage sites by UNESCO.

By June, Lisbon has more than 14 hours of daylight with an average high temperature of 25.7 ˚C (78.3 ˚F) and average lower temperatures of 16.6 ˚C (61.9 ˚F), and visitors are usually welcome with clear blue sky.

Abstracts, to be submitted by January 18, 2019, are welcome in all fields of optics and photonics. ISI indexed proceedings will be published by SPIE and selected papers can be submitted for publication on a special issue of the MDPI Journal PHOTONICS. Revised versions of the manuscripts published at the AOP2019 proceedings book are also eligible to be submitted for publication at the OPA journal
